Chaotic ant swarm algorithm is a novel optimization method, which has the ability of global optimum search. This paper proposes a new parameter estimation method for induction motor based on chaotic ant swarm algorithm. The problem of induction motor parameter estimation is converted to a problem of parameter optimization which could be solved via chaotic ant swarm algorithm. A numerical simulation...
This paper presents a kind of blind watermarking algorithm based on lifting wavelet transform. According to the peculiarities of human visual system, the important coefficients first principle is adopted in the proposed algorithm. The algorithm selects high-frequency coefficients adaptively, and modifies these coefficients according to the watermark values to make the defined eigenvalue in different...
